But that isn't the main message of the last week. Polls are very volatile at the moment, and it is possible for Brown to recover.

And it needs to be about more than neutralising his perceived weaknesses of the Blair years or his opponents' tax plans, though the latter was probably good politics and in a better week would have been seen as such. Brown showed he could deal with crises during the summer, and he probably owes his continued strong personal ratings to that; he must now show how is proactively going to lead the country as a reformer at home - focusing not just on those areas he championed as Chancellor, but on wider public service reform - and as a force for change in the wider world, championing environment and global poverty issues.

If he wants to be a long-term Prime Minister, then he needs to start behaving like one.
